Improvement in fire-extinguishers



UNITED STATES WILLIAM E. BEAsLEY, or LOUISVILLE, KENTUCKY.

IMPROVEMENT IN FIRE-EXTINGUISHERS.

. Specification forming part of Letters Patent No. 129,519, dated July 16, 1872.

To all whom it may concern:

Be it known that I, WILLIAM F. BEAsLEY, of the city ot Louisville and State of Kentucky, have invented certain Improvements in Fire-Extin guishin g Apparatus; of which the following is a specification, and I do hereby declare that the saine is a full, clear,y and exact description of my said invention, reference being had to the accompanying drawing and the letters of reference marked thereon.

My invention relates to certain improvements upon the several patents granted to Joseph Gardner in the years 1871 and 1872 and consists in the devices hereinafter described,effecting results also hereinafter set forth.

vIn the accompanying drawing forming part of this specification, Figure l is a vertical section of an extinguisher of the description before alluded to. Fig. 2 is an elevation of the saine from another point of view. Fig. 3 is a sectional planof the same oii the line m y.

Similar letters of reference indicate similar parts of my invention in all the views.

In the drawing the machine is represented in position for use.

v A is the acid-chamber. B is the soda-chamber. C is the mixingchamber. D and D' are the stop-cocks connecting the chambers A and B with chamber C. E and E are handles for opening and closing the cocks connected by the rod F, so that either handle may be used to .operate both. A single handle, shown in dotted lines and marked E", may be used instead of E and E' connected to or formino` part of the rod F. G and G' are equalizingpipes screwed into the cocks D and D', connecting' the upper parts of chambers A and B with mixing-chamberC. Thecommunicationis closed in like manner as that through the openings I and I', and simultaneously with them. A plain4 aperture can be used instead of the portion otl the pipes entering the mixing-chamber C. M is a pipe in the mixing-chamber C extending from the opening I' nearly to the opening I to promote the rapid and perfect neutralization of the acid, and prevent any particles of soda from passing up and obstructing the pipe G'. H and H' are Stoppers solution Ilow into the mixing-chamber G. and' the gas is generated, which forces the mixture through the hose L. A portion ofthe gas passes up the equalizing-pipes G and G', oc cupying the space left by the receding liquids, and establishing an equilibrium of pressure. When it is desired to stop the tlow through the. hose L the cocks D and D' are closed, which also closes the pipes G and G', and prevents the escape of the gas accumulated in the chambers A and B. In this position the generation of gas is stopped. When the cocks are again opened the force o i' gas abovethe liquids causes them to ow withrapidity into the chamber C, and the generation continues as before. n

The advantages I claim for my invention are the saving of the gas collected in the upper parts of chambers A and B by the closing ot' pipes G and G', when the l'lowot the mixture from the machine is stopped, and the causing of the almost instantaneous iiow of the liquids when the cocks D and D are opened.

My invention is equally applicable to extinguishers carried by the persons using them, and those mounted on wheels and commonly known as village engines.

Having thus described my invention, what I claim as new, and wish to secure by Letters Patent, is 0 The equalizing pipes G and G', in combination with cocks D and D', capable of being opened and closed at the same time and by the same operation as the openings I and. I', substantially as and for the purpose herein specificd.
